List IX R. S. Harrington, C. C. Dahn, V. V. Kallarakal, H. H. Guetter, B. Y. Riepe, R. L. Walker, J. R. Pier, F. J. Vrba, C. B. Luginbuhl, H. C. Harris, & H. D. Ables <1993, AJ, 105, 1571> =1993AJ....105.1571H ================================================================================ Abstract: Trigonometric parallaxes, relative proper motions, and photometry are presented for 122 stars in 111 systems. Of these stars, 70 are brighter than V = 10.0.

An "#" means the quoted value is taken from the literature, and is indicated in the notes. Blank means see the notes. -------------------------------------------------------------------------------- Byte-by-byte Description of file: notes1.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1-80 A80 --- Note Notes -------------------------------------------------------------------------------- Byte-by-byte Description of file: table2.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 3 I3 --- USNO USNO running number 4- 5 2X --- --- Blank 6-16 A11 --- Star Star name 17 1X --- --- Blank 18-130 A113 --- Pos *Reference star positions -------------------------------------------------------------------------------- Notes for file: table2.dat -------------------------------------------------------------------------------- Pos: Reference star positions, measured in arcseconds eastward and northward from the target star, and some alternative designations -------------------------------------------------------------------------------- ================================================================================ (End) Lee Brotzman [ADS] 03-Mar-1995
